Admiral Carls had been a longtime follower of Wegener’s ideas.6 He was the third highest-ranking officer in the navy and a dominant personality, known among his colleagues as the “Blue Czar.” According to Carls, the only way the navy could achieve decisive results in a war was to adopt a two-pronged strategy that concentrated on holding open German sea-routes while attacking British overseas trade. While favoring Wegener’s views, he also considered the acquisition of bases in France the best solution, since the German Navy could not eliminate the effects of a British blockade and pose a threat to that country’s supply routes from Norway. These ends could only be accomplished by capturing the Faeroes or the Shetland Islands, objectives beyond Germany’s capabilities.
In an appraisal of the political-military situation on September 4, 1939, Admiral Carls pointed out the strategic importance of Scandinavia and the danger to Germany if the British Navy was to obtain bases in that area. At every opportunity in September 1939, he emphasized the dangers posed to Germany by British naval and air bases in southern and western Norway. He continually stressed the importance of making plans to counter the possibility of the British establishing themselves on the Norwegian coast.
Raeder claims in his autobiography that “our armament industries would have died overnight” had it not been for the 10 million tons of Swedish iron ore used in German steel production. He goes on to say that the trade through Norwegian waters was going so well that it was taken for granted. He claims:
Never having studied seriously a war with England until that war practically broke out, we had not seriously questioned how far Norway could guarantee her neutrality and the security of the Narvik route in case of war between England and Germany.
In addition, he continued, “Nobody in the Navy, and probably almost nobody else in Germany gave the Norwegian problem a second thought during the first month of the war.”7
These statements are not supported by facts and they misrepresent the navy’s role in planting the seeds and establishing the intellectual framework for the necessity of the Norwegian operation.8 Raeder’s assessment that the war economy would have died overnight if Swedish ore were unavailable is no doubt influenced by his realization that the navy would be the first to suffer if further prioritizing became necessary. By stressing this point in his testimony before the International Military Tribunal, he was undoubtedly trying to depict his activities in the months leading up to the invasion of Norway as responsible pre-emptive planning.
In his testimony at the Nuremberg Trial, Admiral Raeder states that he had not concerned himself with the Norwegian question until he received several intelligence reports during the last week of September 1939.9 He is less than candid. The question of bases in Norway surfaced numerous times in the period after 1935. In a post wargame statement on April 12, 1938, Raeder dealt with the subject of base acquisition for improving the navy’s operational possibilities. The planning committee in 1938 considered a partial occupation of Norway, but its final report concluded that while such a move would improve Germany’s strategic position, it would require substantial forces that could be used better elsewhere. However, the idea was kept alive as an acceptable alternative to the acquisition of bases on the continent’s open Atlantic coasts.
Admiral Carls kept a journal that was read regularly by Raeder, and entries in that journal in September 1939 pointed out the risk of British footholds in southern and western Norway and the necessity for planning German counter-measures.10
The intelligence reports that Raeder refers to in his testimony at the Nuremberg Trial included reports from the German Naval Attaché in Oslo, Lieutenant Commander Richard Schreiber, and a rare personal visit by Admiral Wilhelm Canaris, head of the Abwehr (Department for Foreign Intelligence and Security within OKW) who informed him that there were signs “that the British intended to occupy bases in Norway.”11 The next impetus came from Admiral Carls, who was privy to the same intelligence reports as Raeder. He made a telephone call to Raeder during one of the last days of September to explain that he had prepared a private letter for him. The letter dealt with the dangers to Germany of a British occupation of bases in Norway, and raised the issue of whether Germany should forestall such an attempt by the British. Raeder states that he received the letter at the end of September or beginning of October. He testified at his trial that the letter impelled him to pose a series of questions to the Chief of Staff of the Naval Staff (Seekriegsleitung, or SKL) examining the danger of English occupation of Norwegian bases as well as the pros and cons of a German expansion to the north.12 The questions Raeder posed to the SKL were also given to Rear Admiral Karl Dönitz, the commander of German submarine forces, for comments. Dönitz proposed the establishment of a major submarine base in Trondheim and a fuel/supply depot at Narvik.
The SKL reached mixed conclusions on Admiral Carls’ letter and on the questions posed to them by Raeder. In a document prepared by the Operations Divisions of the Naval Staff on October 9, their opinion was one of caution.13 The naval staff saw no pressing reasons why Germany should establish itself forcefully on the Norwegian coast. First, the occupation of bases on the Norwegian coast would not bring any decisive advantages to Germany’s strategic position, particularly if it were necessary to secure such bases with force. Second, SKL viewed continued Norwegian neutrality as a definite advantage to Germany. They concluded that the German ore traffic would be safer with a neutral Norway than it would be after an eventual German occupation, provided the British forces respected Norwegian territorial waters. The naval staff saw the obvious advantages of Norwegian bases in a naval war against Britain, but they also saw clearly the hazards
